The BolderBOULDER has grown to become one of the largest and most highly acclaimed 10K’s in the world. Almost 1.2 million runners, joggers, walkers and spectators of all ages have gathered over the years to create a spectacle that defies description.
Each year we host 50,000+ participants and 70,000+ spectators at Folsom Field for what we like to call the biggest and best Memorial Day celebration on earth.
The BolderBOULDER is still locally owned and operated, and our dream continues. This event has taken on a life that we never quite envisioned, and it rewards us every year beyond measure. We hope you will join us to celebrate fitness, our country and this great state of ours, Colorado.
Keep up with events, promotions, openings and sales.
